Summary

This presentation by Dr N. Musana, part of the Fetal Medicine Foundation Zimbabwe refresher course, discusses a case of duodenal atresia associated with trisomy 21. The patient, a 27-year-old woman in her second pregnancy, was referred at 32 weeks due to polyhydramnios. Ultrasound revealed a double bubble sign, polyhydramnios, and a ventricular septal defect, along with absent nasal bone, raising suspicion of trisomy 21. Amnioreduction was performed, but the patient went into preterm labor and delivered a live baby boy with low birth weight and features suggestive of trisomy 21. The neonate underwent laparoscopic duodenojejunostomy but unfortunately demised the next day. The presentation reviews the epidemiology, associations, and outcomes of duodenal atresia, emphasizing the importance of prenatal screening and multidisciplinary management. It highlights that while isolated duodenal atresia has good outcomes, the presence of trisomy 21 and associated anomalies can worsen prognosis. The speaker discusses conflicting data on outcomes and stresses the role of early diagnosis and coordinated care.
